neha, 20 May 2013Hi...how can I root my phone from 2.3 to ics or jelly bean. Plz suggest me some easy process a... moreAlso, before step 3 after backup of SMS contacts and personal data on internal SD to PC, you must format the internal SD of your phone.

a must.
2. Place the CyanogenMod rom .zip file on the
root of the SD card:

Transfer your file(s): adb push
YOURROMZIP.zip /sdcard/

If you boot directly to recovery and have
an internal sdcard, you may need to run
adb shell mount /data or mount data
through the recovery menu before transferring.
lmportant: Place the downloaded gapps supplemental packages
(eg Google Apps or kernel) .zip file(s) on
the root of the SD card.
3. Boot to recovery mode on the device by
holding Vol Up & Vol Down & Power or Vol
Up & Home & Power.
4. Once the device boots into the ClockworkMod
Recovery, use the physical volume buttons to
move up and down. On most devices, the
power button is used to confirm your
selection, although for some devices the
power button is used as a "back" button to
go up one level, in which case the home
button is used to confirm the selection.
5. Select the option to wipe data/factory reset .
6. Select install zip from sdcard .
7. Select choose zip from sdcard.
8. Select the CyanogenMod file you placed on
the sdcard. You will then need to then
confirm that you do wish to flash this file.
Important: Install the gapps package using the same method.
9. Once both installations are finished, return
back to the main menu, and select the reboot
system now option. The device should now
boot into CyanogenMod.
